Abstract

A wideband phased array antenna includes an array of dipole antenna elements on a flexible substrate. Each dipole antenna element has a medial feed portion and a pair of legs extending outwardly, and adjacent legs of adjacent dipole antenna elements have respective spaced apart end portions to provide increased capacitive coupling between the adjacent dipole antenna elements.
Each leg has an elongated body portion, and an enlarged width end portion connected to an end of the elongated body portion. A phased array antenna with a wide frequency bandwidth and a wide scan angle is obtained by utilizing tightly packed dipole antenna elements with large mutual capacitive coupling.
